There are new technologies to assist blind people with navigation. One blind inventor has a system where he is followed by a drone while running on a track with painted lane lines. The drone monitors his position in the lane and sends feedback to wrist bands that alert him if he is getting close to a line on either side. Allows him to run in the lines, which is a spatial activity. This was a proof of concept for now and I doubt anything like that could work for a motorcycle. However, like cochlear implants for hearing impaired, we could be on the cusp of breakthroughs for vision loss.
I hope she enjoys the ride.
